Sorry to resurrect this thread, but I am intrigued by "not 100% of the OS upgrades themselves were successful...some VM Boot issues, but totally unrelated to ZCM" and here's why. I am in the situation of having 5 ZCM primaries at 2008R2. In my test bed I took an 11.4.3 primary running 2008R2 and did an inplace upgrade to 2012. It "worked fine" with the teensy-weensy problem of not allowing me to log into the server, except in safe mode. Not handy. You'd probably think that having had that result I wouldn't try it on a live server, but I thought, what the heck. Did it on a production server, and same result. It's not a disaster, since I can easily revert to pre-upgrade. However, doing inplace upgrades would be way faster than doing five new servers from scratch and copying a fairly large content repository manually.
So I'm just wondering if by any chance the problems you were referring to might have been the inability to log on to the server except in safe mode, and if so, if a fix for that was found. You said it didn't seem related to ZCM, and yet the two ZCM servers I tried had the same result. Since there is nothing but ZCM installed on them, it's hard to imagine it isn't somehow related to ZCM. Seems to me the ZCM agent has a certain amount of interaction with the GINA... could that be related?
Wasn't quite sure what you meant by "user spoke", but when I overrode the ZENworks Agent settings for that server (using ZCC) and cleared the checkbox for "User Management Installed" under "Agent Features" and issued a refresh: voila! my login screen returned. Very nice. I'm guessing that once I install ZENworks 2017 I can put that setting back to "install"?
Thanks so much for your help!
Yes you can put it back, but normally I would not recommend enabling the "User Spoke" on most Server PCs unless they are designed to be used by End Users, such as a terminal server.
Helps avoid a case where you accidentally push Desktop PC User settings to a server.
Normally User specific Bundles/Polices are not needed to be delivered to you ZCM Primary Servers, Your Database Servers, Domain Controllers, etc.. etc...
